PNEUIVIATIC GRIP OR HANDLE.

SPECIFICATION forming part of Letters Patent No. 599,131, dated February15, 1898.

Application 1ed October 3, 1896. Serial No. 607,757. (No model.)

To all whom t may concern:

Be it known that I, ADELMOUR W. KING, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Improvement in Pneumatic Grips or Handles, ofwhich the following is a specication.

My invention relates tov grips or handles for bicycles. These handles asusually constructed have been made of cork, leather,'

hard rubber, composition, or two more of said materials, and the samewere-not yielding to such an extent as to relieve the hand of thevibration of the machine in riding.

The object of my present invention is to supplya grip or handle thatyields to the hand and lessens vibration.

In carrying out my invention I employv a double inflatable rubber gripor handle composed of concentric tubular interior and eX- terior rubberportions permanently united together at their ends. A valve convenientlylocated is employed to allow air to be forced between the concentrictubular portions for inflating the grip or handle. The double iniiatablegrip or handle surrounds the ends of the bicycle handle-bar or otherfoundation or base, and I employ fel-rules at the respective ends of thegrip or handle to protect the ends and impart a finish and to serve as areceptacle for the valve.

In the drawings, Figure l is a longitudinal section showing my inventionas adapted to a bicycle handle-bar, and Fig. 2 is a crosssection at theline a: w of Fig. 1.

a d represent the concentric tubular interior and exterior portions ofthe double iniiatablev grip or handle, the one part a being within theother part, a, and the permanent connectionsbeing at the respectiveends. These tubular portions are preferably made of soft rubber or softrubber molded on a fabric base, as this construction will wear betterand possesses greater strength. The outer portion a' is provided with avalve b of any compact and desirable construction to allow air to beforced in between the parts a d' for inating the grip or handle.

The double inflatable grip or handle is shown as applied upon the end ofa bicycle' In this instance the inner and 'i at 2 at one end, while theother ends of said portions are made with heads 4 5, the head 4 of theinner tube coming against the end of the handle-bar, if the same is ofwood, or against the surface of a plug 6, inserted in the metal bar e,to provide abearing for the soft rubber. The head 5 is adjacent to andoutside of the head 4 and is provided with a valve b to allow the handleto be inflated by air introduced between the tubular portions.

The connecting-webs 8 are shown as at the outer end of the handle,although they may be employed at the inner end, the outer end being themore essential. The valve b is se.- cured in the head 5 at the end ofthe outer tubular portion a.. The respective ends of the doubleinflatable handle are protected and covered with ferrules c cl,preferably of hard rubber, Celluloid, or other similar mav terial placedover said tubular portions before the grip or handle is inflated.

The ferrule d issecured to the handle by a set-screw 3, and the ferrulec is provided with a removable disk c2 to cover the valve and impart afinish to the handle.

My improved grip or handle can be inflated more or less at the pleasureof the user, and the same yields or conforms more or less to the hand asthe hand grasps the handle, and the same reduces to a minimum thevibration of the machine that would otherwise be communicated to thehand.

The combination with a rigid supporting core or bar, of a pneumaticrubber grip or hanf) dle formed of inner and outer rubber tubeslconnected together at one end, the inner tube being closed across at theother end and ref? ceiving said core or bar, and webs between the outerand inner tubes adjacent to said closed end, the outer tube being formedwith a head outside the closed end of the inner tube and avalve thereinto allow the grip to be inflated, and ferrules receiving within them therespective ends of the pneumatic grip, substantially as set forth.
